Andrianavoay (meaning "noble crocodile" in Malagasy) is an extinct genus of teleosauroid from the Bathonian (in the Middle Jurassic), probably from the Isalo III Formation of Madagascar.^[1]

The type species, A. baroni, was originally named "Steneosaurus" baroni by ET Newton in 1893 on the basis of a partial skull listed as "NHMUK PV R 1999",^[2] and an associated osteoderm from Andranosamonta, Madagascar.^[2] In her unpublished 2019 thesis, Michela Johnson coined the nomen (ex dissertatione) Andrianavoay for S. baroni.^[3] The genus name was published in 2020.^[1]
